lfliii@ Application filed May 13,

To all whom t muy' concern:

Be it known that l, JOHN lifiunnRANT, a citizen of the Tdnited States, and resident of Sedalia, in the count);v of Pettis and State of Missouri, have invented certain new and useful improvements in Grain-Car Doors, of which the following is a specification.

This invention relates to freight ear doors, and more especialhT to grain doors, it being theiobject of the invention to provide in combination with an ordinarT outer sliding door, an inner door mounted for sliding movement along the inner side of the car wall to and from the door opening and provided with means for the convenient filling of the car with grain and for relieving the pressure in ogeninpn the car, for starting the flow or discharge or grain, or for taking out the merchandise or freight which liams or `wedges against the inner door, soithat the pressure can be relieved and the door slid open.

further object is the provision of such a grain door of novel and improved construction, iny connection with novel means for holding the door closed, rendering` the same grain tight, and resisting the'outward pressure against the relief door, the construction also being such that leakage and theft (withseal of the doors) are eliminated.

, Jfinother object is Vthe 1provision of hinged bars Lto swing` between the door posts or jambs and tlic inner grain door and arranged to overlap tue relief door and hold it closed against outward pressure, as well as retaining the grain door in place and providing a tight joint between said door and the door frame.

vi-"igstill further object is the provision of novel means for holding saidv bars either against the door or out ofthe way against the door posts.

- lilith the foregoing and other objects in viewY which will be apparent as the description proceeds, the invention resides in the coi truction and-arrangement of parts hereinafter described and claimed, it being` understood that changes can be made within theV scope of what is claimed without departing from the spirit of the invention.

. The invention is illustrated in the accompanying drawings, wherein- `Figure 1 is an outside View showing the inner grain door in closed position, and the .outer door slid open.

Figure S is a similar view showing the bar swung against the fame.

The present improvements arc incorporated .in the ordinair)7 car construction, witlu out requiring prohibitive alterations. The door frame forming a part of the sidewall of the car includes the vertical door posts or vjambs 7 as usual at the opposite sides of the door opening, and an ordinary outer door 8 is suspended for longitudinal movement along the"outer side ofthe car wall to and ifrlom the door opening, as usual. It is prefcomprises a plate secured to andprojecting upwardly from the upper edge of the door and having a head, the flanges of which upon rollers 'l0 mounted within the channels il of the track Vwhich extends along car wall above the door opening from the vertical door stop 12 to a suitable distance toward the opposite side of the door opening, permitting the door to slide freely The lower edge of. the door 8 'is retained against the sill bvmeans 'of guides 18.

Coming to the inner grain door 14, which may be ofwood or other suitable construction, this door is also mounted for longitudinal sliding movement, and is located at Ythe inner Vside of the car wall, being also groove, the door 14 when it is slid open, although this housing 13 need not be used in all cases. The chief object in using the housing 13 is to prevent merchandise from preventing the opening of the door 14, although this is not strictly necessary, because access can be had into the car through the relief door to remove the merchandise. A. vertical stop 13 is secured to the inner side of the car wall at that side of the opening opposite to the housing` 13 to limit the movement of the door 14 when slid to closed position. Y

The door 14 has the vertical stiles 19 at its side edges forming the shoulders 20 extending vertically and facing one another at the outer side of the door 14 to move substantially flush with the door posts or jambs 7, as seen in Figure 4. These stiles 19 are adapted to bear against the inner sides of the jambs 7 to take up the outward pressure against the door.

The door 14 is provided near its upper end with a lling opening 21 normally closed by the door 22, hinged, as at 23, to swing open outwardly, and any suitable lock 24 can be used for holding the door 22 closed. This door when swung open permits the grain to be 'delivered into the car behind the door 14 by the usual chute or the like. Y

The door 14 is further provided with a relief opening 25 extending from a point between its upper and lower ends to the lower end thereof and being of a width to extend close to the shoulders 20. This openf ing 25 is closed by a relief door embodying upper and lower sections 26 and 27, the upper section of which is hinged, as at 28, to the door 14 at the upper edge ofthe opening 25 to enable the relief door to swing open outwardly and upwardly for relieving the pressure and starting the llow of grain, or permitting the merchandise or freight to be taken out from behind the door. The sections 26 and 27 are hinged together, as at 29, permittingthe joint to break outwardly.

A sill plate 30 is provided on the sill of the car at the lower end of the door opening, and is preferably flush with the floor of the car. `This sill plate 30 has a longitudinal slot or groove 31 over which the door 14 is movable, and the lower edge of the relief door section 27 has a depending flange or lip 32 movable in the slot or groove 31. The outer wall of the groove 31 is vertical or square for the flange 32 to bear outwardly against, thereby receiving the outward pressure against the lower edge of the relief door, and preventing said lower edge from being forced open outwardly by the pressure of the grain or freight. The inner wall of the groove 31, however, is inclined, whereby should any grain, ore or other matter accumulate and even harden within said y in being closed will cause the anges at the lower end thereof to OrCe the accumulation out of the groove. In this way, the groove 31 will be cleared of matter accumulated therein, thereby avoiding the objection of the possible difficulty in sliding the door 14 closed should ore, cement or other matter collect and harden within the groove. Naturally, the lower flanges of the door in striking the matter within the groove will, by the endwise pressure, break it and force same upwardly and inwardly out of the groove. Plates 33 are secured to the lower end of the door 14 at the stiles, and have depending flanges 34 to also .move in the groove 3l.

Locking bars 35 are provided at t-he opposite sides of the door opening for holding the inner door i4 and its relief Vdoor closed. liar-h of these bars comprises the plates 36 and 37 with a filler plate 38 between them, and the plate 36 forms the leaf of a hinge, being provided with the hinge butts 39 slidably and rotatably embracing a vertical hinge rod 40 extending through the hinge butts 41 of a hinge leaf 42 secured to the inner side of the respective post or jamb 7. The hinge butts 41 are spaced apartsuificienllj-.f to permit of vertical movement of the hinge butts 39 and the bar`35, this bar extending along the post or jamb atthe inner corner thereof and therefore being slidable longitudinally of itself or vertically of the car wall. These bars are swingable between the door 14 and jambs 7 in the ici-ner between them, and said bars are hinged to the jambs directly adjacent to the inner sides thereof so as to swing flatly against the door 14, from one edge of each harto the other edge, and with the hinged edges of the bars presented to and abutting' the shoulders 20, as seen in Figure 4. This will iiri'nly hold the door 14 in place, and 'l i sill plate 30 has, as a part of the dooi.` fi LJue, a slot or recess 43 at each end of said plaie below the respective bar 37 and extending from the corresponding jamb 7 toward the opposite side of the door frame to receive the lower end of the bar 35 from edge to edge. Thus, when the bars 35 are swung against the door 14, the vertical movement thereof, permits them to drop or slide downwardly with their lower ends litting snugly in the slots or recesses 43,V

thereby holding said bars against the door. The bars when swung against the door 14 overlap the ends of the relief door, thereby preventing outward movement thereof, and the lower ends ofthe bars 35 in tting in t ie slots or recesses 43 will resist the outward pressure against the relief door where the greatest security is necessary owing to the pressure from within the car. The bars when swung against the door 14 rest flatly against the door practically flush with the llO stiles 19, and when the bars 35 are swung.`

away from Vthe door 14 they swing -atly against the jambs 7, permitting. the relief door to swing open outwardly, as when starting the discharge of grain or the removal of freight or merchandise in emptying the car. Furthermore, when the bars 35 are swung against the jambs, the door 14 can also vbe slid openf By the provision of the movement of the lower ends of the bars `35 into the slots or recesses 43, the lower ends of said bars are rmly braced and held against outward sagging or springing movement under the pressure against the relief door, andthe flange 32 will prevent the lower edge of said relief door from springing or sag.- ging outwardly between the barsI 35.

Means are provided for securing the bars to the door 14 above the relief door, to assist in holding the parts in place. Thus. nuts 44 are embedded in the door 14, and suitable bolts are insertable inwardly through the bars 35`t0 lengage the nuts 44 and clamp said door and bars together, as seen in Figure 4. The bars are preferably provided with means for. the insertion of the bolts permitting them to be readily alined with the nuts 44. Thus, the plates 36 and 37 of each bar have openings 46, andv the plate 38 has a Alarger ,opening` 47 in which .a ring` 4 8 is movable, the opening thereof being exposed through, the. openings 46. Thus, the bolt-45 can be readily inserited into the ring 48which can be moved vertically and horizontally within the opening 47 so that the bolt can b e readily brought into engagement with the nut. Thus, even though the bar 35 Ais movable vertically, and there is possibility ofrelative-horizontal displacement between the b ar 35 and door 14, the bolt can be shifted toconveniently introduce the same into the nut 44.

ln order to hold the bars out of the way against the jambs 7 when they are not in'use, the sill plate 30, forming. a part of the door frame, has `transverse slots' or recesses 49 extending along the janibs and into which the lower ends `of the Vb ars 35 can `drop when th-ey are swung flatly against the jambs, thereby preventing said bars from. being swung away from the j ambs and damaged during the load-ing or unloading ,of the car. Furthermore,.nuts I50 can be embedded in thc j ambs 7, so that the bolts 45. can be inserted in the opposite direction through the bars 35 `and screwed into the nuts 50 for clamping Athe bars against the jambs. lt

Y will also provide means forY holding the bolts 45 when they are disconnected from the door 14. lt is preferable to use a standard bolt, so that the loss thereof enables another ordinary lbolt to beV used.'

1t is also desirableto use avlock 51 for controlling. the movement of the outer and inner doors. VThis lock embodies a casing or supporting member. 52 secured ,in any suitable inanner to thepost or jambV 7 across which the doors are movable, and at that side of the jramb opposite to the door opening. This member 52 has a. slot or opening v53 Aextending therethrough transversely of the car wall, and latch rings 54 and 55 are disposed in the opening 53 for transverse movement through the car wall, the joint diameters of the two rings being slightly greater than the thickness of the car wall or the space between the doors 8 and 14. These rings are retained in the member 52 by means of bolts 56 extending therethrough, yet permitting of the inward and outward movement of said rings.v ln using .this lock, the outer door 8 is provided at its inner side and near that edge adjacent to the door opening when the door 8 is opened, with a recess or slot 57 to receive the ring 55, .as seen in Figure 4. Therefore, after the door 8 is slid open, the ring 55 will be able to enter the recess 57, so that when the door 14 is slid open it will push the ring 54 outwardly, and the ring 54 in contacting with the ring will thrust the latter outwardly into the recess 57. The door 14 Awhen open will prevent the rings from moving inwardly, so that the outer door 8 cannot be slid closed until the inner door is firstclosed, thus releasing the inner ring 54. The outer door can then be slid closed, and the rings will be forced inwardly and held in this position, with the ring 54 projecting inwardly into the path of the door 14. Therefore, when .the outer door is in closed position, the inner door cannot be opened by a person within the car, for purposeI of theft, because the inner ring 54 will prevent the inner door from being slid open as long as the outer door is closed. However, when the seal of the outer door is broken and said door slid open, this will, b v bringing the recess 57 opposite to the ring 55, permit the rings to move out fardly for opening the inner door. Y

Figures 7 and 8 illustrate a niodilication, wherein the locking bar 35 is hinged to the door 14, instead to the door frame as in Figure 4. Thus. the hinge plates or leaves 42 are secured to the Stiles 19 of the door 14. instead of being secured to the door posts or jambs 7 Otherwise, the construction is the ,same as that above described, being noted, however, that the locking bars 35 are carried by the door 14, so that these bars will move with the door when it is slid open and closed. The bars 35 are movable into the recesses 43 and 49 in the sill plate 250, and said bars are also fastened to the door 14 or jambs 7 by means `of the bolts 45, which can also be used for holding the bars to the door 14 when it is slid.
